Root Test for for Convergence of an Infinite Series

The Root Test serves as a fundamental tool in the analysis of infinite series, offering insight into their convergence properties. Introduced as a counterpart to the Ratio Test, it explores the behavior of the nth roots of a series' terms, providing a criterion for convergence based on these roots' limits. Through the examination of these limits, mathematicians ascertain whether a series converges or diverges, crucial for understanding the behavior of various mathematical constructs. In this essay, we delve into the mechanics of the Root Test, its applications, and its significance in the broader landscape of mathematical analysis.
